After staffers at the club noticed sports drink bottles containing chemicals inside the toilet and called police, it was determined the facility was being used to make meth by the "shake and bake" method of causing a chemical reaction in a single container, KFOR-TV, Oklahoma City, reported Wednesday.

Three bottles were found, two of which exploded before detectives arrived, the television station said.

"If someone would have been in the porta-pot when it happened, they might have gotten hurt by the flying plastic and the chemicals," said Purcell police Detective Cpl. Scott Stephens.

Investigators said they had a lead on one suspect, but others could be involved. No arrests have been made.
